LOCK-HINGE.

SPECIFICATION forming part of Letters Patent No. 232,128, datedSeptember 14, 1880.

Application filed August 19, 1379.

To all whom it may concern:

Be it known that I, ADOLPH H. HUGUET, a resident of the city of BatonRouge, parish of East Baton Rouge, and State of Louisiana, have inventeda certain new and useful Improvement in Combination Hinge and Look; andI do hereby declare the following to he a full, clear, and correctdescription of the same, reference being bad to the annexed drawings,making a part of this specification.

This invention is designed as an improvement on that class ofblind-hinges shown in Letters Patent dated June 14, 1870, No. 104,359;and the improvement consists in a flanged leaf provided with a recess atthe junction of the leaf and flange, and a sliding bolt working in atransverse groove, in combination with a similar flanged leaf providedwith a knuckle to work in the recess of the opposite leaf and having afiat face or shoulder and a groove for the sliding bolt in the closedand opened positions, as will be hereinafter more fully set forth.

In the annexed drawings, Figures 1 and 2 represent the same as appliedto a frame and shutter, the latter shown as partially opened in thefirst figure, and as opened to its full limit in the second figure.Perspective views of the hinge, with sections disconnected, arerepresented in Fig. 3.

The sections or parts A B are each provided with a rear projection, asat(] O, the said pro jections furnished with one or more countersunkholes, in order that they may be secured in position by additionalscrews passing at right angles into the frame or shutter, as shown.

The invention consists in providing one seetion say Bwith a notchedprojection or knuckle, D, which is constructed on a line with the eye ofthe section and about midway between the ends thereof. On a level withthe aforesaid projection D the opposite section,A, is recessed, as at b,to permit of the said projection operating therein. This section A isalso provided across its face with a horizontal recess, E, in which isfitted a sliding plate or bolt, F, by means of which the hinge is lockedin any given position.

To facilitate the movingof lhe bolt it is furnished with a button orstud, a, which, when the hinge is closed, rests in a hole, f, that ismade in the section B to receive the same, and prevents the opening ofthe shutter, even though the outer portion of the hinge be broken.

In order to guard against the bolt being accidentally or willfullywithdrawn from its recess, the latter may have a horizontal slot made inthe same, as shown in dotted lines at m, and

the stud a be screwed through the said bolt' until its point shall enterthe aforesaid slot, and thus limit its movement.

It will be observed by reference to Fig. 1 of the drawings that theshutter is retained in an opened position by the sliding bolt F restingin the vertical groove h of the knuckle, and in Fig. 2 that the shutteris opened, in which position it is kept by the sliding bolt restingagainst the outer flat face, m, of the knuckle.

By this construction of a hinge ot' the class described I am enabled tosimplify the parts and cheapen the manufacture.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

The combination, hereinbefore described, of the leaves A and B, of thesame thickness, adapted to be fastened to the edge and face of the jamb,the former grooved transversely at E, and provided with the recesses band sliding bolt F, and the latter provided with the knuckle D, withfiat face m, and vertical groove, as shown, and for the purpose setforth.

In testimony whereof I have hereunto signed my name.

A. H. HUGUET.
